Powering a Lionel 455 oil derrick

The + or - labels on the terminals would make sense only if it had to be run on one polarity of DC; but it will run on either AC or DC.  I'm sure most are operated on AC.

Hey Ralph:        I have the same one, it'll work either way.    later.

Does the wiring of this accessory have any special connection requirements. The bottom is not marked with  " + " and   "- "  next to the posts.  Does it matter which goes to which? 

Does the same hold true for the modern versions 6-12930/6-12848?

 

Thanks
